Review above is wrong. No problem reading with WiFi turned off. Must be his problem. Restriction imposed by authors means sometimes hyphenated words don't change when page size is changed, but no big problem reading.

DO NOT BUY THIS BOOK! Due to publisher's restrictions, you can only read it when you have a Wifi signal. This makes it useless otherwise. I wasted my money, don't waste yours.

The best way I can tell you how suspenseful the novel was is to say that at one point I was so scared and thoroughly involved while reading, that when my belly made a giggling sound it scared me half to death and I jumped! And that's the truth ...

The amount of research these guys must put in to create a story like this amazes me. There are no holes where details and storyline fail to flow. There is a lot of information to comprehend but you don't have to be a total geek to enjoy this. Great story.
